RBF - Radial Basis Functions

RBF is a code that implements the idea of radial basis functions. RBF was written by Edward Kansa.

RBF references the MINPACK library.

Files you may copy include:

• rbf.f90, the source code.
• rbf_gnuplot_commands.txt, a set of commands generated by RBF that instructs GNUPLOT to display the data.
• rbf_kansa.ps, a paper by Edward Kansa that discusses the method.

The list of routines includes:

• RBF implements the radial basis function method.
• FFUN returns the value of one of six different functions of X.
• DFUNDX returns the derivative of one of six different functions of X.
• D2FUNDX returns the second derivative of one of six different functions of X.
• GNUPLOT writes out a file for input to the GNUPLOT graphics package.
• HLSREC calculates the functions at X.
• DECOMP computes a PLU decomposition of a matrix.
• SOLVE solves a linear system whose matrix has been decomposed by DECOMP.
